LEVI L. RAYMER, OF LIMA, OHIO, ASSIGNOR OF ONE-THIRD TO JOHN S. HUNTER,OF LIMA, OHIO.

WINDOWSCAFFOLD.

Application filed November 17, 1910.

To all whom it may concern:

Be it known that I, LEVI L. RAYMER, a citizen of the United States,residing at Lima, in the county of Allen and State of Ohio, haveinvented certain new and useful Improvements in 'Windowscaffolds, ofwhich the following is a specification.

This invention relates to improvements in window scaffolds, moreparticularly to devices of this character employed by persons whencleaning windows and for like purposes, and has for one of its objectsto improve the construction and increase the efliciency and utility ofdevices of this character.

Another object of the invention is to provide a simply construct-eddevice of this character which is capable of adjustment to enable theoperator to reach all parts of the window from the exterior of thebuildmg.

Another object of the invention is to provide a device of this characterwhich may beadjusted to windows of various sizes and to buildings havingwalls of various thicknesses.

Another object of the invention is to provide a device of this characterwhich may be folded when not in use to occupy a relatively small space.

With these and other objects in view the invention consists in certainnovel features of construction as hereafter shown and described and thenspecifically pointed out in the claims; and, in the drawingsillustrative of the preferred embodiment of the invention, Figure 1 is aperspective view of the improved device applied, with portions of abuilding including a window opening and frame; Fig. 2 is a sideelevation of the improved device applied with the window sill insection; Fig. 3 is a detail plan view of portions of the improved deviceillust-rating the construction of the window frame and sill clampingmechanism; Fig. at is a section on the line 1-4 of Fig. 3.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The improved device is constructed wholly of metal, preferably of gas orsteam piping where y the maximum of strength Specification of LettersPatent.

with the minimum of weight is secured, and comprises a supporting baseframe formed with spaced side members 1011 and a transverse outer endmember 12. The base frame may be of any required size, but the sidemembers 10-11 will be spaced apart at a distance equal to the smallestwindow in connection with which the device is liable to be employed, andwill thusbe adapted to windows of any size.

Means are provided in the improved device for detachably coupling theside members 1011 to a window, and as these securing devices areprecisely alike, the descrip tion of one will suffice for both. Each ofthe securing devices comprises a section of piping 13 having a rod 14slidable in one end and secured in position by a set screw 15 and eachrod provided with an inwardly directed toe 16 for engaging against oneedge of a window casing, indicated at 17 adjacent to the window stool,indicated at 18. Slidable upon each rod 14: is a sleeve 19 having abearing foot 20 and secured adjustably to the member 13 by a set screw21. The foot 20 is designed to bear against the inner face of the windowframe, indicated at 22, and operates in opposition to the toe 16 of therod 1 1. By this simple means it will be obvious that the member 13 maybe firmly clamped to a window frame and its casing. The side members1011 are provided, respectively, with collars 23, through which themembers 13 pass, the collars 23 being provided with set screws 24 sothat they may be adjustably connected to the members 13. Engaging overthe member 13 at each side of the collar 23 is a double hook devicehaving a forked and hooked upper portion 25 and a single hooked lowerportion 26. The two hooks 25 engage over the member 13, while the singlehook bears beneath the window stool 18 and against the facer member 27By this simple means the frame 10-11 12, together with the structuresupported thereby, is firmly clamped to the window stool, and readilydetachable therefrom when required.

Connected to the members 1011, preferably near their outer ends, aresleeves 28-29, the sleeves being provided, respec tively, withperforated ears 3031, between which the lower ends of upright members32-33 are pivotally supported. The members 32-33 extend normallyvertically and are connected at their upper ends by a transverse member34. Slidably engaging, respectively, upon the members 10-11, are sleeves35 36, and secured adj ustably to the members 10-11 by set screws 37-38.The sleeves 35-36 are provided, respectively, with upwardly directedears 39-40 to receive the lower ends of brace members 41-2. At theirupper ends the brace members are swingingly connected at 43-44: to themembers 32-33. By this means it will be obvious that the members 32-33,together with their braces, all-42, may be folded into parallelrelations with the members 10-11, the object to be hereafter explained.Mounted to swing upon the transverse member 12 of the base frame is abrace frame comprising spaced side members IS-46 and a transverse endmember 47. The member 47 is provided with bearing toes or feet 48adapted to engage against a building beneath the window opening.Slidable upon the side members 10-11 of the base frame are sleeves49-50, and slidable upon the brace members 45-46 are other sleeves51-52. The sleeves 49-50 are provided with perforated cars 53 54, whilethe sleeves 51-52 are provided with similar perforated ears 55-56, theears just described being utilized to swingingly support braces 57-58.By this means the brace frame 45-6-47 may be adjusted to any requiredextent to control the relative position between the brace members andthe frame members, and thus adapt the device to walls of variousthicknesses, as will be obvious.

Slidably engaging upon the vertical members 32-33 are other sleeves59-60, while still other sleeve devices 61-62 are slidably engaged withthe members 32-33 at a higher point than the sleeves 59-60. The sleevedevices 59-61 are united by a vertical member 63, while a similarvertical member 64: unites the sleeves 60-62. Swingingly connected tothe sleeves 59-60 is a platform, represented as a whole at 65, theplatform being preferably formed, like the remaining portions of thedevice, of sections of gas piping. The member 65 is oblong in,

outline and covered by a suitable foot support, indicated at 66. Securedupon the side members of the platform are sleeves 67-68, the lattersleeves being provided with perforated ears to receive the folding bracesections 69-70, while similar folding brace sections 71-72 areswingingly coupled to the sleeves 61-62. The brace members 69-71 arehingedly united at their free ends, as shown at 73, while the bracemembers 69-70 are similarly jointed, as shown at 74;. By thisarrangement it will be obvious that the platform 65 is firmly supportedin horizontal position from the sleeves 61-62, but is foldable therewithwhen required. By this means the platform 65 may befolded against themembers 63-64 and in parallel relations to the vertical members 32-33.

A Windlass 75, of suitable material and proportions is mounted forrotation between the sleeves 61-62 and provided with an operating crank76 and a stop ratchet and pawl 77-78. Connected at 79-80 to thetransverse member 34 of the vertical frame are cables 81-82 which areconnected at their ends to the windlass 75. rangement it will be obviousthat when the crank 76 is rotated in one direction the cables 81-82 willbe wound upon the drum and thus elevate the platform 65 to any requiredextent within the range of the members 32-33, and held at any point bythe operation of the ratchet and its stop pawl.

The improved device is simple in construction, can be inexpensivelymanufactured of material that is readily procured in the open market,and does not require any expensive attachments to complete thestructure. It will thus be noted that a simply constructed windowscaffold is produced which may be readily connected to the window andwill support aperson in safety and in convenient position to clean,paint, or otherwise work upon the exterior ,of windows, and by simplyactuating the crank 76 the supporting platform 65 may be adjusted toenable a person to conveniently reach any part of the window whenrequired. hen required the improved device may be readily folded into acomparatively small space for transportation or storage.
